The Louse That Ended the Old Vineyard

Phylloxera is a root-feeding aphid native to the eastern United States. American vines evolved alongside it and tolerate it. European vines never met it, have no defence, and die when the roots are attacked. It arrived in France in the 1860s on imported plant material, reached Burgundy in the 1870s, and within twenty years most of the Côte was gone.

Nothing in the chemical armoury of the period touched it. Flooding worked where the land was flat enough, which the Côte is not. Injecting carbon disulphide into the soil worked partially and was dangerous and expensive. The crisis lasted long enough to empty villages, and it is the reason there was a generation of Burgundians in South America.

The solution, when it came, was a compromise that nobody wanted. Graft a European fruiting scion onto an American root: the root resists the insect and the scion makes the wine. It was fiercely resisted, partly on the belief that the American root would ruin the flavour, and partly because accepting it meant admitting that the vineyard could not be saved as it was. It works. Every vine in Burgundy today grows on American roots, which is a fact worth sitting with before any conversation about tradition and continuity.

What deserves more attention than the grafting is everything else that changed at the same time. Replanting an entire region within a few decades is an opportunity to reconsider every decision, and growers took it. Rows that had been irregular were straightened and spaced for horses, and later for tractors. Planting density changed. Propagation changed: instead of layering shoots from whatever vine happened to be there, growers took cuttings from selected plants, which is the beginning of the massal and clonal selection debates that continue now. The old dense, mixed, irregularly planted vineyard simply ceased to exist.

It is the largest uncontrolled experiment in the region's history, and it has never been undone. Four substantial variables (rootstock, density, propagation method and row orientation) all changed together, and each of them affects vigour, ripening and crop level. To claim that a domaine's style runs unbroken from the 1850s is to claim to taste through all four simultaneously.

This also puts a hard ceiling under the old-vine romance. There are a handful of tiny ungrafted parcels kept as curiosities and essentially nothing else. A vineyard described in the Côte as very old is nearly always post-1900. Pre-phylloxera bottles, when they turn up and are genuine, are not an older version of the same wine; they are the product of a different agricultural regime, and tasting one tells you about that regime rather than about continuity.

The honest reading of the whole episode is that Burgundy is a reconstruction. The map survived because the map is about land, and land does not die. The vineyard did not survive: it was rebuilt from the soil up by people making decisions under emergency conditions, with incomplete information, in a hurry. Everything since has been built on those decisions.

Which is, in its way, a more interesting story than unbroken tradition. The claim that the ground reasserts itself through a change of rootstock, a change of density, a change of propagation and a change of orientation is a strong claim about terroir, and it is one the region has actually tested, involuntarily and at enormous cost. Most people who invoke tradition on the Côte are invoking something that began around 1890.
